Microsoft Word, rebuilt free and open
WordCraft is a free, open-source rebuild of Microsoft Word with track changes and styles, and your AI assistant can work inside it directly.
A Word you could actually own
Somebody went and rebuilt Microsoft Word from scratch. It's called WordCraft, it comes from the team behind ArtCraft, and it's free and open source. It looks familiar on purpose. It has the ribbon tabs across the top and styles that update as you work. It also has track changes for when your lawyer or your co-founder starts scribbling in the margins.
It's still young. The latest version added style management and a "Select Recipients" feature, the kind of thing you'd reach for when sending the same letter to a list of people. The stated goal is full parity with Word, which is a big ambition. Plenty of people on GitHub seem to like the idea.
The part that made me lean in
WordCraft speaks MCP. That means an AI assistant like Claude can operate it directly. It could open a document, apply your house styles, tidy up a contract or prepare those letters. You wouldn't be copying text in and out of a chat window. The AI would actually be working in the file, a bit like a junior assistant sitting at your desk.
For a small business, that's a quiet shift. Proposals, menus, contracts and client reports could all be produced with an AI's help, properly formatted, in a free tool.
Words worth knowing
- Clean-room rebuild: recreating software by studying how it behaves, without copying its original code.
- MCP (Model Context Protocol): a shared plug that lets AI assistants use other apps, a bit like USB for AI.
- Open source (Apache 2.0): the code is public, and this license lets people use and build on it freely.
Something to sit with
It's early, so don't cancel anything yet. But if you write the same handful of documents every month, bookmark github.com/storytold/wordcraft and watch it grow. Picture which of those documents you'd happily hand to an AI.
